The MAP2K4 antibody is a crucial tool for studying the mitogen-activated protein kinase kinase 4 (MAP2K4), also known as MKK4 or SEK1. a serine/threonine kinase in the MAPK signaling pathway. MAP2K4 acts as an upstream activator of c-Jun N-terminal kinase (JNK) and p38 MAPK, playing a pivotal role in cellular responses to stress, inflammation, and apoptosis. It is involved in diverse physiological processes, including cell proliferation, differentiation, and survival, and has been implicated in cancer, neurodegenerative diseases, and immune disorders.
Antibodies targeting MAP2K4 are widely used in research to detect protein expression, phosphorylation status, and subcellular localization via techniques like Western blotting, immunohistochemistry, and immunofluorescence. These antibodies help elucidate MAP2K4's regulatory mechanisms, such as its activation by upstream kinases (e.g., MAP3Ks) and its interaction with scaffold proteins. Commercial MAP2K4 antibodies are typically validated for specificity across human, mouse, and rat samples, with some detecting phosphorylated forms (e.g., Thr261/Ser265) to assess activation.
Dysregulation of MAP2K4 is linked to tumor progression, making its antibodies valuable in cancer research. For instance, loss-of-function mutations in MAP2K4 are observed in certain cancers, suggesting a tumor-suppressive role. Researchers also explore MAP2K4 as a potential therapeutic target or biomarker. Validation of antibody specificity through knockout controls or siRNA silencing is critical to ensure reliable results, given homologous epitopes in related kinases. Overall, MAP2K4 antibodies are indispensable for dissecting MAPK signaling dynamics in health and disease.
